Intel Neural Compute Stick 2


An Intel Neural Compute Stick 2 (NCS 2) just turned up. It will be interesting to see how it compares to the earlier version. The software supporting it is now OpenVINO which is pretty interesting as it makes it relatively easy to move models across multiple hardware platforms.

The NCS 2 is really the best edge inference hardware engine that is generally available as far as I am aware. Hopefully, one day, the Edge TPU will be generally available and there seem to be many more in the pipeline. Typically these edge inference devices do not support RNNs or related architectures but, in the short term, that isn’t a problem as CNNs and DNNs are probably most useful at the edge at the moment, being very effective at compressing audio and video streams down to low rate information streams for example.

A nice feature of the NCS 2 is that it is easy to connect multiple examples to a single powerful CPU. The combination of a reasonably powerful CPU along with dedicated inference hardware is pretty interesting and is an ideal architecture for an rt-ai Edge node as it happens.
